I have been reading a great deal through the years about this liberation theology movement, which is in truth is a leftist/fascist view of religion, especially Christianity. An excellent book that discusses this in some detail is Modern Fascism: The Threat to the Judeo-Christian Worldview by Gene Edward Veith, Jr.

The State by Franz Oppenheimer (1864-1943) was recommended to me years ago by friends as a Libertarian classic of political science. However, having just finished this tome, I now suspect that some of them did not actually read the book, but instead only read passages from it.
The "Right" versus "Left" convenient but capricious political arrangement came from the seating position of delegates to the National Assembly during the French Revolution, but it is at times a confusing concept and too often subject to media and academic bias and even misinformation. I have found it easier to have a political spectrum based on degrees of government control.
